LOUVER CONSTRUCT I ON Fil ed June 19, 1950 s Sheets-Sheet 5 Patented June 20, 1933 UNITED STATES PATENT OFFICE EARL PHILLIP JONES, 01 FORT LAUDERDALE, FIDRIDA, ASSIGNOR TO GATE CITY SASH & DOOR COMPANY, ,OF FORT LAUDEBDALE, FLORIDA, A CORPORATION OF FLORIDA LOUVER CONSTRUCTION Application filed June 19,

details and features of construction and combinations tending to increase the general etficiency and the desirability of a louver construction of this particular character.

To the foregoing and other useful ends,

the invention consists in matters hereinafter set forth and claimed and shown in the accompanying drawings, in which- Fig. 1 1s a front elevation of a set of louvers or blinds for a window, or other similar opening, embodying the principles of the invention.

Fig. 2 is a horizontal section on line 22 in Fig. 1 on a larger scale.

Fig. 3 is an enlarged vertical section on line 33 in Fig. 1 of the drawings.

Fig. 4 is a view similar to Fig. 3, showing a single set of louver shutters in closed position.

Fig. 5 is'a side elevation of one of the movable connecting members to which the ends of the louver slats are connected.

Fig. 6 is a plane view of one of the louver slats, on a larger scale, with the middle portion thereof shown broken away for convenience of illustration.

Fig. 7 is an edge view of the shutter shown in Fig. 6 of the drawin s.

Fig. 8 is a front elevation o a door provided with a set of louvers or shutters embodying the principles of the invention.

Fig. 9 is an enlarged vertical section on line 9--9 in Fig. 8 of the drawings.

Fig. 10 is an enlarged vertical section on line 10-10 in Fig. 8 of the drawings.

Fig. 11 is a horizontal section on line 11- 11 in Fig. 10 of the drawings.

As thus illustrated, referring to Figs. 1

1930. Serial N0. 462,172.

to 7 of the drawings, the invention comprises a rectangular frame 1, having a plurality of openings therein. The sides of said openings are preferably provided with stationary cleats 2 as shown. The cleats 3 are vertically movable in said frame, and in said openings. Louver slats or shutters 4 have their ends provided with pivots 5 mounted in the cleats 2, and said shutters have their ends provided with pivots 6 mounted to turn in the cleats 3 previously mentioned.

Therefore, of course, when the cleats 3 are moved up and down the shutters or louver slats 4 are tilted about their fixed axes provided by the pivots 5 previously mentioned.

When the cleats 3 are moved downwardly the slats are opened. -Preferably, as shown in Fig. 3 of the drawings, the cleats 2 and 3 are similarly and relatively formed to engage each other along a zigzag line, whereby the shutters are each nearly in a Vertical plane when the same are in closed position.

To open the shutters, the cleats 3 are moved downward, by any suitable means. It will be understood, of course, that any suitable means, such as friction in the pivot hearings, or anywhere else, can be employed for holding the shutters in closed position, or in partially opened position. When the shutters are open, the cleats 3 bear against the inner side 7 of the frame as shown and are supported in this position by the frame, thus holding the shutters in horizontal planes, thereby providing the maximum space or opening between the shutters. When the slats or shutters are closed, the pivots are all uniformly, spaced vertically, whereby the cleats 2 and 3 are duplicates in formation.

As shown in Fig. 6, the shutters may have metal ends 8 provided with said pivots, if such is desirable or necessary.

As shown in Figs. 8 to 11 inclusive,fltl1e construction is similar, but in this case the rectangular frame 9 takes the form of a door. In this case, the cleats 10 are stationary, like those previously described, while the cleats 11 are vertically movable like those previously described. The shutters 12 are rigid with the pivots 13 and 14, as previously described, and the mode of operation of the louver or shutter thus provided is similar to that previously explained. In each form of the invention, a horizontal cleat is preferably rovided to form a stop for the lower bla e or shutter of the louver construction, when the shutters are in fully closed position. In this way, the

, shutters fold in overlapping relation and shed water from the outside. Furthermore, if desired, screens 16 ma be provided in the frame, outside of the s utters, and in this way screens are provided outside of the louver shutters, which are controllable from the inside of the house or building.

Thus it will be seen that a simple and inexpensive form of louver or shutter construction is provided, as a part of a door .or window or other closure, of such character that the louvers or shutters can be controlled from the inside of the house or building, it being understood that the rectangular frame shown in Figs. 1 to 4 inclusive, or the rectangular frame shown in Fig. 8, may occupy a position in the door or window opening, and may be mounted in any suitable or desired manner, so as to be elther movable or stationary in the window opening or the door opening.

What I claim as my invention is:

In a louver or shutter construction for doors and windows and other openings, the combination of a plurality of louver slats disposed in parallel relation to each other, a stationary pivot at each end of each louver slat, and an up and down movable pivot at each end of said louver slat, stationary means engaging said stationary pivots, whereby these plvots are all in a fixed vertical plane, together with movable controlling means engaging the movable pivot of each louver slat to control the motion of each slat about a stationary horizontal axis provided by its stationary pivots, said controlling means being movable downwardly and away from the vertical plane of said stationary pivots, to open the slats, and stationary means to support said controlling means in the open position of the slats, said stationary and movable pivot engaging means comprising a stationary cleat for engaging the stationary pivots, and a movable cleat for engaging the movable pivots, the two cleats having duplicate zigzag interen aging edges, whereby the two cleats in e ect interlock when the slats are in closed position, each cleat having its engaging edge of curved zigzag form, roviding compound curves, and the engaging edge of one cleat being a duplicate of the engagin edge of the other cleat, whereby the mova le cleat moves toward and away from said stationary cleat.
